The reaction of metallated 1-phenyl-1H-tetrazol-5-yl sulfones and aldehydes gives good yields and stereoselectivity of trans-1,2-disubstituted alkenes when potassium or sodium hexamethyldisilazide is used as base and 1,2-dimethoxyethane is used as solvent.
金属化1-苯基-1H-四唑-5-基砜与醛的反应,在以六甲基二硅氮钾或钠为碱且以1,2-二甲氧基乙烷为溶剂的条件下,提供了良好的产率和反式-1,2-二取代烯烃的立体选择性。
